In medicine,
3D printers began to be used several years ago, mostly in orthopedics. With the
help of plastic MRI images, exact copies of fractures were printed, so that
doctors could study on these models and later began to make models of organs.

In
mid-April, Japanese scientists presented an exact copy of the human liver made
of plastic, where all its vessels and nerves were reproduced. The tumor was
also printed. According to this model, the doctors determined exactly how the
tumor should be removed so as not to damage the function of the organ.

Similar
experiments on the creation of accurate models are carried out in the European
Union. In the European School of Urology in Barcelona, ​​the scientists are
going to create plastic analogs of the kidneys and hearts in the same way in
order to figure out how to treat them in the best possible way. They are also
sure that in 10-15 years most of the complex operations will be performed by
this method, by scanning, production of models. Only after the meticulous
studying they could work with the body.

Another area
in printing is the development of individual prostheses and even plaster
bandages that fit more closely to the patient’s body and provide better
fixation of fractures.

Thanks to
the seven-millionth development of robotics and the reduction in the cost of
using 3D printing technology, in recent years, prosthetics have attracted a lot
of attention.

Open Bionics
has created an amazing prosthetic arm on a 3D printer, which is currently being
tested by Daniel Melville as part of a pilot program that was launched as part
of an international electronics exhibition. Melville was allowed to use the
prosthesis for five days and perform various tasks with it, testing its
capabilities. One of the features of the new prosthesis is the ability to shake
hands, “give a high five” and carefully take small objects. By the way, to his
grea joy and the joy of his relatives, Daniel almost immediately adapted to the
prosthesis and constantly walked and shook hands with everyone he met.

Before
creating the prosthesis, the right hand of Daniel was first scanned. This
process took only 20 minutes. Scanning was necessary in order to create the
most appropriate 3D-frame, the installation site of the prosthesis. The
required frame was printed on a 3D printer in 40 minutes. The complete creation
of the prosthesis required only 40 hours instead of several weeks, which are
usually required to create conventional prostheses. After printing on the
prosthesis, various robotized parts were installed and the electromagnetic
sensors of the prosthesis were connected to the muscular and nerve endings of
Daniel’s hand.

While Daniel
was enjoying the presence of a second functional arm (before that, he had to
wear a conventional cosmetic prosthesis, not even a quarter of what a new
prosthesis could do), Joel Gibbard was already looking for ways to improve his
invention, making the prosthesis stronger, lighter and rid of external wires
that are present on the first prototype.

Some algae
have a special photosensitive organ, the so-called “eye.” Like human
eyes, the “eye” of algae puts into operation the component of the
photosensitive protein rhodopsin-2.

With its
help, the algae determine different changes in light and begin to move toward
the light, where there are more favorable conditions for photosynthesis. So,
scientists have isolated the photosensitive protein ChR2 from algae and since
the mid-2000s they have been using it in optogenetics, exploring the work of
nerve cells by activating them with light.

In its pure
form, the substance was isolated in 2017, which helped to analyze its properties
more thoroughly. It was found that the protein regulates the biosynthesis of
micro-RNA and helps in chromatin remodeling.

These
processes contribute to subcellular recovery, so the experts intend to
transplant the ChR2 gene to the organs of vision of blind patients. The gene is
placed inside the vector and injected into the eyes, with the result that the
previously non-sensitive cells are transformed into photosensitive cells with a
limited ability to see.

Scientists
from the United States were able to detect and isolate components from the
composition of Arabidopsis thaliana algae that are suitable for developing
vision medications. It is a unique medicine that is based on simple organisms
living in the water and is undergoing clinical research. It is not yet known
when people who do not have the ability to see can use it. But there is a fact
that at the primary testing against the blindness this medicine has shown its
effectiveness.

Experts for
Medicorum said that algae of the species Chlamydomonas reinhardtii and
Arabidopsis thaliana have the ability to react to light. Organisms do not have
their own organs of vision but use a primitive “eye” that allows them to sense
the sun and move beyond its rays in order to start photosynthesis.

Also, the
action of the protein was tested on laboratory animals. As it turned out, after
such a therapy, the eyesight of the experimental was restored to some extent. A
little later, a substance isolated from algae was injected with a thin needle
into the retina of a volunteer blinded by retinitis pigmentosa. As a result,
cells that lost sensitivity were transformed into photosensitive cells, and the
patient could see the dim outlines of objects.

The patient
could not fully restore his sight, but the progress was significant. However,
it is too early to say that this is possible in the case of a person who is
blind due to damage to the photosensitive cells of the retina. The fact is that
the modified ganglion cells cannot distinguish the object in color. As a matter
of fact, mice do not need it, since they are twilight animals, and in the
morning and in the evening due to the fact that it is dark, the colors are not
particularly distinguishable. But after all, a person shows mainly daily
activity, color vision is vital for him.

Experts
intend to continue research to bring the technology of blindness to perfection.
To test algae-based optogenetics, a group of 15 volunteers who have retinal
pigment degeneration is recruited .

Fear is the normal response we have to an immediate threat of danger or pain. While it’s completely normal to feel anxious, people with anxiety attacks experience excessive fear and worry of everyday situations, with little or nothing to provoke them.

According to the National Institute of Mental Health, approximately 30% of American adults experience an anxiety attack every year Anxiety attacks can cause people to avoid the situations that trigger the symptoms interfering greatly with their daily activities. Anxiety attacks are sudden and overwhelming, but there are proven ways to lower your anxiety and think more clearly. Here are 5 best ways to stop anxiety attacks;

1. Control your breathing One of the most common symptoms of an anxiety attack is rapid breathing and shortness of breath. The first thing you should try when you have an anxiety attack is to breathe deeply in order to control your breathing pattern. Immediately you recognize you are having an anxiety attack practice the following technique;

Place your hand firmly on your stomach

Take a deep breath for about 5-7 seconds •Hold your breath for about 3-4 seconds

Exhale gently with pursed lips•Repeat the technique a few times If possible, open a window and breath some fresh air and keep practice your breathing.

The trick is to control your breathing. If you control your breathing, you will prevent rapid breathing which can significantly increase your anxiety and other unpleasant symptoms.

2. Acceptance Acknowledging the source of your discomfort will go a long way in reducing your anxiety attack. Remind yourself that you are experiencing an anxiety attack and it isn’t a catastrophe. Accepting that the attack, no matter how unpleasant, will end after a short period can significantly help someone remain calm. If you have experience anxiety attacks before, try to remind yourself that previous attacks passed and this too will pass.

3. Practice Mindfulness Most anxiety attacks happen when people imagine something bad happening either in the past or in the future. Mindfulness brings you back to the present and it can help you manage your situation better. Take deep breaths and concentrate on what is happening now

If you are new to practicing mindfulness and are having a hard time concentrating, use the following technique;

Take a seat and place your hands on your thighs.

Name out loud 5 things you can see, then 5 things you can hear and finally five things you can touch

Repeat the technique a few times until you feel you are back to the present

4. Go to your happy place Close your eyes and imagine being in the place where you feel happiest and most relaxed. Think about how calming the place usually is for you. Try to refocus all your energy there. Remember how it felt to be so happy and relaxed. The goal is to focus all your attention away from what triggered the anxiety attack in the first place.
